Your thoughts about my niche idea

My niche worksheet:
Weight Loss with Keto, for Christians
My clients learn to balance their hormones, reduce insulin resistance and become fat adapted by following the KETO/LCHF way of eating.
They work on their mind/body connection by using the Model and studying the Holy Scriptures to find their true identity as beloved children of God.
My 9 week program is named Shifting Inside Out. It consists of a “devotional/progress tracker” type notebook, one-on-one coaching or group coaching, membership to the private facebook support group and access to me as needed for private coaching.
I have been coaching groups and individuals (women mostly, but a few men) with this program since Sept. 2017.
I would love to know your thoughts about my niche and I would appreciate your suggestions.
Thank you for all that you have done for me and I’m looking forward to Coaches Training in May!
